我发现Daniel Storm在另一个帖子中提供了这段代码。对不起，我不能在那里问我的问题，因为我还没有足够的声誉可以发表评论。每次单击与displayAd关联的按钮时，代码都应显示广告。但是，在模拟器和实际设备上进行测试时，广告仅在第一次单击按钮时显示。请帮忙......
var iAdInterstitial = ADInterstitialAd() // Our ad
var iAdInterstitialView = UIView() // View to present our ad in
var adLoaded = false // Bool to keep track if an ad is loaded or not
override func viewDidLoad() {
super.viewDidLoad()
setupAd()
}
@IBAction func displayAd(sender: AnyObject) {
if (adLoaded) {
// We have an ad that is loaded so lets present it
self.view.addSubview(iAdInterstitialView)
iAdInterstitial.presentInView(iAdInterstitialView)
}
else {
// No ad has been loaded
print("Ad not loaded")
}
}
func setupAd() {
// Set presentation to manual so we can choose when to present the interstitial
// Setting this will also fetch an interstitial ad for us
self.interstitialPresentationPolicy = ADInterstitialPresentationPolicy.Manual
iAdInterstitial.delegate = self // Set the delegate
// Make our view the same size as the view we will be presenting in
iAdInterstitialView.frame = self.view.bounds
}
func requestNewAd() {
// This will fetch an ad for us
ResizingTestViewController.prepareInterstitialAds()
print("Requesting new ad")
}
@IBAction func presentAdButton(sender: AnyObject) {
if (adLoaded) {
// We have an ad that is loaded so lets present it
self.view.addSubview(iAdInterstitialView)
iAdInterstitial.presentInView(iAdInterstitialView)
}
else {
// No ad has been loaded
print("Ad not loaded")
}
}
func interstitialAdDidUnload(interstitialAd: ADInterstitialAd!) {
// Kinda works as expected
// Sometimes is called prematurely
// Sometimes takes minutes after ad is dismissed to be called
print("interstitialAdDidUnload")
// Get new ad
adLoaded = false
iAdInterstitialView.removeFromSuperview()
requestNewAd()
}
func interstitialAd(interstitialAd: ADInterstitialAd!, didFailWithError error: NSError!) {
// Failed to load ad so lets try again
print("didFailWithError: \(error)")
requestNewAd()
}
func interstitialAdWillLoad(interstitialAd: ADInterstitialAd!) {
// There is an ad and it has begun to download
print("interstitialAdWillLoad")
}
func interstitialAdDidLoad(interstitialAd: ADInterstitialAd!) {
// We got an ad
print("interstitialAdDidLoad")
adLoaded = true
}
func interstitialAdActionShouldBegin(interstitialAd: ADInterstitialAd!, willLeaveApplication willLeave: Bool) -> Bool {
print("interstitialAdActionShouldBegin")
return true;
}
func interstitialAdActionDidFinish(interstitialAd: ADInterstitialAd!) {
// Done with this ad. Lets get a new one
print("interstitialAdActionDidFinish")
iAdInterstitialView.removeFromSuperview()
adLoaded = false
requestNewAd()
}
